OIL-BURNER.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed March 5, 1914. Serial No. 822,770.

To all whom it may concern:

Be it known that I, BERNARD Fnnsn, a citizen of the United States,residing at Lemoore, in the county of Kings and State of California,have invented a new and useful Improvement in Oil-Burners; and I herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates to oil burners wherein petroleum or distillatesthereof are converted into gas before ignition takes place. The gasgenerated in the known burners of this kind, is under more or lesspressure which causes the carbon residue in the heated generator tobecome hard, and causes the small openings, from which the gas escapes,to clog and gradually close. I

My invention eliminates these objections by providing a gas generatorthat allows the gas to escape freely therefrom without the gas becomingignited therein. The advantage I obtain thereby is that the sedimentformed in the generator does not harden, but is of a soft spongyconsistence, easily removed with a wooden or other poker, and

that the gas can expand before being ig nited.

In the accompanying drawings-Figure 1 is a perspective view of myburner. Fig. 2 is a horizontal section on dotted line K. Fig. 8 is avertical section on dotted line X Similar letters refer to similar partsin the several views.

' Gr is the gas generator open at a, a, it has an extension G forcommunicating heat to the box G. The generator has three legs T, two ofwhich are shown in Fig. 3, the third being on the side of sectionremoved.

C is a receptacle for holding the generator and other parts, it alsoserves as a pan to hold a small quantity of oil for preliminary heatingof the generator.

E is a cover forming a draft channel 0 on the upper part of thegenerator G, the

lower draft channel C, beingformed by the receptacle C and the generatorby means of the legs T, T,'T, which support the generator in thereceptacle.

F covers the open end of G leaving sinal. spaces a, a, between the openend of G and the cover F. Cover F has a tube F attached to it whichextends inside of and to the farther part of the generator box.

D are the lugs on the receptacle C and b are bolts holding the parts E,F and C together, the same bolts may be used to fasten the whole to astove or furnace. The tapering lugs D give the whole an incline, causingthe oil to flow to the lowest part.

A feed pipe and needle valve should be attached to F to regulate theamount of oil that is fed to the heated generator through the tube F. p

The gas generated in the box Gr passes freely through openings a, a, andis then carried by the draft through the channels c, c, to be mixed withair. The draft in the channel 0, 0, prevents ignition in the generatorbox. the end of the generator box and through the space C.

By permitting thus the mixing of air and hot gas complete combustion isobtained, no soot is formed at any place nor is smoke visible from thechimney.

I have invented and made and sold burners having open generator boxesand draft channels for more than two years prior to my presentinvention. The generators of my prior invention had the oil supply pipeas an integral part thereof; this proved unsatisfactory on account ofthe feed hole clogging. I therefore cannot claim broadly the mostimportant part of this burner: an open generator box and the draftchannels.

IVhat I claim as my present invention and desire to secure by LettersPatent is:

Ignition takes place near 1. In an oil burner, a receptacle, a genoratortherein, a cover forming a draft channel on the upper part of thegenerator, there being a lower draft channel between the generator andthe receptacle, and a feed tube separate from the generator andextending thereinto.

2. In an oil burner, a receptacle, a generator therein, a cover forminga draft channel on the upper part of the generator, there being a lowerdraft channel between the generator and the receptacle, and a feed tubeseparate from the generator and extending thereinto, there being avertical space between the inner end of the receptacle and thegenerator.
